Also in 2267 the Excalibur was assigned to Sector 221-G and surveyed the planet Priatia. At this point, the commanding officer was Anton Harris. This was one of Excalibur's last missions, a few months before the disastrous M5 war games in 2268. This was also during the time before the Thallonian Empire became very aggressive about keeping outsiders away. (NFnovel: After the Fall)
